"JSF Good!" Says Rick Hightower If you have not looked into Spring yet, it is time. Here is why you should! Grady Booch once said that the great thing about objects is that they can be replaced. The great thing about Spring is it helps you replace them. With Spring, you simply inject collaborating objects called dependencies using JavaBeans properties and configuration files. Then it's easy enough to switch out collaborating objects when you need to. Spring allows you to dynamically add services to objects called aspects. This is similar to the Decorator Design pattern, but does not require you to recompile your code base to apply these services. This allows you to replace objects with objects that enhance the originals. The ability to inject collaborating objects is often called IoC (inversion of control). Thus, Spring is an IoC container. If you follow the latest ... (more)

Programming Languages for the JVM

Back before Java became popular, I was a C++ bigot. I programmed in nothing but C++. I lived, ate and breathed C++. If it wasn't C++, it was rubbish. I thought C++ was the alpha and omega of object-oriented programming. I had "operator overloading" for breakfast, "templates" for lunch and "multiple inheritance" for dinner, and I always went back for seconds. Then a funny thing happened. I got a new job at another company as a C++ programmer. But they pulled the old bait and switch. Once I started working, someone suggested writing a good portion of a large project in a scripting ...

i-Technology Viewpoint: Google's GWT "May Change Web Development Forever"

Time is a brutal enemy of youth and exuberance. Time makes cynics of us all. Time is the universal truth serum that reveals all authenticity. Time will tell, but the announcement yesterday by Google may change the faces of AJAX development, strike that, Google's announcement may change web development for evermore. This cynic heard an announcement yesterday that changed his viewpoint and beliefs on the future of web development. Certainly, in the recent past, the chances of doing an entire application in AJAX seemed remote for the vast sea of developers. The thought of writing a ... (more)

BeanShell & DynamicJava: Java Scripting with Java

The past three articles in this series have highlighted the strengths of scripting languages. They're interactive and dynamic, and allow you to experiment, debug and prototype solutions quickly. However, the most common response when I speak to die-hard Java fanatics is, "Yeah, but I'll have to learn another language and I already know Java" (I consider myself a die-hard Java fanatic to a degree). To be honest, this is a barrier that most won't cross. But what if you could have the best of both worlds? What if you could have your cake and eat it too? Well, in a sense you can. Y... (more)

Developing with DCOM & Java

Developing distributed components with Java and DCOM (distributed component object model) simplifies developing distributed applications. If you know CORBA or RMI, DCOM is easy to learn. Microsoft's Java Virtual Machine makes developing COM and DCOM components painless. DCOM currently ships with the Microsoft Windows NT 4.0 and Windows 98 operating systems. It's also available for download for the Windows 95 operating system. In addition, there are efforts to make DCOM available on a number of UNIX platforms. Many of the Java application server providers, such as BEA's WebLogic J... (more)
